GERMANY — February 23, 2011 — The INDEX at Geneva is one of the most important exhibitions for Trützschler Nonwovens. As the focus of the INDEX is on hygienic applications and light webs, we will present our latest developments in these fields. Technological developments in these fields are

•    Lines for chemical bonding
- New Fleissner Double Roller Unit for liquid and foam impregnation
•    Lines for thermal bonding (through-air bonding/thermobonding)
- Reduction of the energy consumption
•    Spunlace Lines
- special applications (e. g. Spunbond - Spunlace)
- natural fiber webs with Erko Random Card EWK413, Erko Airlay Card EWKL and Fleissner Lean Jet

Newest innovations in the field of nonwovens technology:

Double Roller Unit for liquid and foam impregnation
In our constant efforts to adapt the products of the Trützschler Nonwovens Group to the requirements of the market, the foam impregnation padder and the liquid impregnation padder from Fleissner's product range have been redesigned.

The construction of the Double Roller Unit was used as basis to realize a unit for optimum application of chemicals either in liquid form or as foam with high speed. 

Based on standard roller pipes the roller diameter and surface are chosen depending on the working width and process parameters.

The rollers can be cooled to prevent to a large extent the adhesion of the applied chemicals. The pressure is generated pneumatically. Where necessary, the machine is equipped with a roller-bending-compensation-system which compensates the bending of the rollers under load.

The new construction guarantees an optimal and uniform application of the chemicals across the entire working width.

Energy saving in thermal processes (drying & bonding)
Trützschler Nonwovens focuses its development work more and more on the reduction of energy costs. A modern line becomes even more efficient not only through an optimal line layout and by using highly efficient drive systems but in particular by additional energy recovery measures. Trützschler Nonwovens will present concepts for the reduction of the energy consumption in their own production lines.

Natural fiber webs with the Random Card EWK413
Natural fiber webs are becoming more and more interesting. Whether it is cotton, wool, or bast fibers such as hemp, kenaf or flax, the future belongs to them too! Our special card EWK413 for random technology particularly excels in processing these fibers. It is particularly suited for the subsequent hydroentanglement with Fleissner LeanJet, simplifies the randomized fiber orientation and at the same time offers a high degree of flexibility with regard to the web weights.

A clear advantage is that only two roller diameters are necessary which consequently significantly shortens the time for clothing replacement.    

Fibers: 0.7 - 30 dtex
Fiber length: 15 to 60 mm
Web weight: 25 - 140 g/m²
Output: < 400 kg/h/m
Working with: < 3,800 mm           

For heavy-weight products in the range of 120 - 230gsm (e.g. cotton pads) the Erko Airlay Card EWKL is available.   

Hydroentanglement with the AquaJet - New applications for the hydroentanglement technology were found and further developed.
At the INDEX Trützschler Nonwovens will present new products and further developments of the AquaJet. It is a combination of Spunbond-Spunlace and Splittable Fibers - Spunlace.

Trützschler Nonwovens Technology Center:
The Trützschler Nonwovens Technology Centers in Dülmen and Egelsbach are specially equipped towards the requirements of our customers. We can demonstrate all technologies from fiber preparation, web formation, web bonding to web finishing for product development and customer trials.
